Security Medium — Strava Heatmaps have Unintended Consequences

The popular exercise tracking app Strava regularly produces a really cool heat-map that shows where most people run, cycle, swim etc.. The data is anonymised, so it all seems like some innocent fun. The latest version of the heatmap was published back in November, and no one thought it was a problem.

All the cool kids are moving to Discord for podcasting and chat, and so is the NosillaCast. We’ll hear a CES interview with August about their smart locks (spoiler, I’ve got one). TJ gives us his review of the HiFi ELITE Super66 headphones. Back to CES with the Velco Connected Handlebars for bicycles, and the new fleet of Jabra wireless headphones. In Security Bits, Bart Busschots brings us up to date on Spectre and Meltdown, along with an interesting lesson about spareness and density of data collection regarding how the exercise app Strava showed military installations.
